DNN-Based Speech Presence Probability Estimation for Multi-Frame Single-Microphone Speech Enhancement

ICASSP 2020accepted

Multi-frame approaches for single-microphone speech enhancement, e.g., the multi-frame minimum-power-distortionless-response (MFMPDR) filter, are able to exploit speech correlations across neighboring time frames. In contrast to single-frame approaches such as the Wiener gain, it has been shown that…

Subspace-Based Speech Correlation Vector Estimation for Single-Microphone Multi-Frame MVDR Filtering

ICASSP 2020accepted

Aiming at exploiting the speech correlation across consecutive timeframes in the short-time Fourier transform domain, the multi-frame minimum variance distortionless response (MFMVDR) filter for single-microphone speech enhancement has been proposed. This filter is designed to avoid speech distortio…

Utilizing spectro-temporal correlations for an improved speech presence probability based noise power estimation

ICASSP 2015accepted

For the enhancement of speech degraded by noise, accurate estimation of the noise power spectral density (PSD) is indispensable, especially if only a single microphone signal is available. Fast and accurate tracking of the noise PSD is particularly challenging in highly non-stationary noise types, s…
